Distributed measurement-based quantum computation [article]

Vincent Danos and Ellie D'Hondt and Elham Kashefi and Prakash Panangaden
2005 arXiv   pre-print
We develop a formal model for distributed measurement-based quantum computations, adopting an agent-based view, such that computations are described locally where possible.  ...  Since measurement-based quantum computation is inherently distributed, this allows us to extend naturally several concepts of the measurement calculus, a formal model for such computations.  ...  However, a formal language for distributed quantum computation is lacking.  ...
